GASOLINE-FILTER ATTACHMENT FOR MOTOR VEHICLES.

Application filed September 9, 1924. Serial 'No. 7 36 759.

Too whom it may concern:

Be it-known that I, FHENRY'G. LAMBERT, a citizen of the United States,residing at Roll. in the county of Pontotoc and State of (Oklahoma,haveinvcnted certain new and useful Improvements in a Gas-oline FilterAttachmentfor hlotor Vehicles, of which the following is aspecification.

This invention relates to improvements in gasoline filter attachmentsfor motor vehicles andhas for its primary object taprovide a simple.andeliicient device which is placed in the feed line between the'vacuumank and the pipe loading to the-carburetor for the purpose of filteringthe gasoline before the same is delivered to the carburetor.

Another important object of the invention is to provide a gasolinefilter attachment of the above mentioned character, wherein the same isof such a construction as to enable the parts to be readily disassembledfor the purpose of removing the filter and cleaning the same.

A further object of the invention is to provide a gasoline filterattachment of the above mentioned character. which at all times will bepositive and efficient in its op eration and Will not in any wayinterfere with the operation. of the motor vehicle or the feeding of thegasoline from the vacuum tank to the carburetor.

A still further object is to provide a gasoline filter attachment of theabove mentioned'character, which includes a means for cutting off the.gasoline supply to the carburetor when the filtering member has beenremoved for cleaning purposes.

A still further object is to provide a gasoline filter attachments ofthe above mentioned character, which is simple in construction.inexpensive, strong and durable and furthermore adapted for the purposesfor which it designated.

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing forming a part of this specification and inwhich like numerals designate like parts throughout the same:

Figure l is a side elevation of my im proved invention showing the samein position with respect to the vacuum tank and the -teed pipe, and

Figure 2 a vertical sectional view ot i the attachment. 7

In the drawingwherein for the purpose .of illustration shown thepreferred embodiment of my invention, the numeral 1 designates the-bodyof the filter attachment, and the eame is provided at its upper end withthe reduced threaded portion 2 for attaching the body member to thevacuum vtank A. The portion between the reduced Ithreadcdportion 2 andthe main body portion 1 is substantially square as illustrated at 3 forthe purposeof providing a means whereby the tool may be used inattaching the body member to the bottom ofthe vac uum tank.

The body member is provided with a longitudinally extending bore 4, thelower portion-oi the body member 1 is provided with an enlarged recess 5and -the purposethereol' will be presently described. The enlargedrecess 5. is adapted to communicate with the bore tof the body member 1as is clearly illustrated in Figure 2. Threaded into the lower portionof the recess 5 is the plug 6. The lower end of the plug is reduced andexternally threaded as illustrated at 7 and is adapted to be connectedto the feed pipe 13, the portion above the reduced threaded portionbeing substantially square as illustrated at 8 to facilitate theattaching of the plug to the feed pipe. The plug 6 is also provided witha longitudinal bore 9 and the same communicates with the bore 4 formedin the body 1 in the manner as illustrated more clearly in Figure 2.

The upper portion of the plug 6 is spaced from the inner wall 10 of theenlarged recess 5 and adapted to be removably supported therebetiveen isthe filter designated generally by the numeral 11. In this manner the fiter may be ren'iovabliy supported within the enlarged recess 5 andbetween the oomnuinicating bores 4 and 9 respectively so as to cause thegasoline passing from the vacuum tank through the body and the plug tobe filtered before entering the feed pipe B and being delivered to thecarburetor (not shown). The sediment will be collected by the filter andthe filter may be easily and readily removed from' the enlarged recessby removing the plug 6 Whereby the. filter may be cleaned or replaced.

For the purpose of cutting off the supply of fuel from the vacuum tankto the feed pipe when the parts of the attachment are disassembledparticularly when the filter is being cleaned, I provided the body witha transversely extending tapered bore 12 through which extends a rotaryvalve 18, the same having the opening 14 thereof adapted forcommunication with the bore 4 of the body 1 when in its normal position.A handle 15 is formed on the enlarged outer end of the valve forfacilitating the ope ation thereof and a coil spring 16 is associatedwith the smaller end and the adjacent portion of the body for normallyholding the valve in an ope-n position.

The provision of an attachment of the above mentioned character, in thegasoline feed line between the vacuum tank and the carburetor willinsure the supply of gasoline to the carburetor in a clean statefreefrom dirt and other foreign substances, thereby increasing theefliciency in the operation of the engine. Furthermore, the provision ofgasoline filter attachment of the above mentioned character, enables thesame to be readily and easily disassembled without the loss of anyconsiderable length of time and labor.

While I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claim.

Having thus what I claim is In combination with the fuel feeding meansof a motor vehicle including a vacuum tank and feed pipe, of a filterattacl ment associated therewith, comprising a body member, the upperend thereof being threaded into the vacuum tank, said body member havinga longitudinal bore, the lower portion of the body having an enlargedrecess therein communicating with the bore, a plug threaded into thelower portion of the recess, the lower end of the plug being connectedto the feed pipe, said plug having the longitudinal bore thereincominunicating with the aforementioned bore, a

to the feed pipe, said means comprising a rotary valve mountedtransversely in the body above said recess.

In testimony whereof I aliix my sign ature.
